Regulating supreme court recusals

This article presents a critical analysis of the approach of the U.S. Supreme Court to recusal motions aimed at one of the Justices of the Court. The catalyst was the controversy arising from the weekend duck-hunting trip of U.S.Vice-President Richard Cheney and Supreme Court Justice Antonin Scalia, after which Justice Scalia denied a motion to recuse himself from a pending case in which his hunting partner, Mr Cheney, was a party. This startling decision is final and conclusive since the Supreme Court refuses to intervene in such decisions. Such an approach by the Court is untenable and contrasts starkly with that of the House of Lords, which did not shrink from disqualifying Lord Hoffmann on grounds of bias in the Pinochet case. A comparative study of comparable common law jurisdictions exposes the U.S. Supreme Court as an island of isolation over this issue. It also provides accessible solutions that are disarming in their simplicity. The particular responses that are commended in this article are formalized self-regulation and substitution

Study of Charm Baryons with the BaBar Experiment

We report on several studies of charm baryon production and decays by the BaBar collaboration. We confirm previous observations of the $\Xi_c^{'0/+}$, $\Xi_c(2980)^+$ and $\Xi_c(3077)^+$ baryons, measure branching ratios for Cabibbo-suppressed $\Lambda_c^+$ decays and use baryon decays to study the properties of the light-quark baryons, $\Omega^-$ and $\Xi(1690)^0$.Comment: 8 pages, 5 postscript figues, contributed to the Proceedings of ICHEP200

B mu G@Sbase - a microarray database and analysis tool

The manufacture and use of a whole-genome microarray is a complex process and it is essential that all data surrounding the process is stored, is accessible and can be easily associated with the data generated following hybridization and scanning. As part of a program funded by the Wellcome Trust, the Bacterial Microarray Group at St. George's Hospital Medical School (BμG@S) will generate whole-genome microarrays for 12 bacterial pathogens for use in collaboration with specialist research groups. BμG@S will collaborate with these groups at all levels, including the experimental design, methodology and analysis. In addition, we will provide informatic support in the form of a database system (BμG@Sbase). BμG@Sbase will provide access through a web interface to the microarray design data and will allow individual users to store their data in a searchable, secure manner. Tools developed by BμG@S in collaboration with specific research groups investigating analysis methodology will also be made available to those groups using the arrays and submitting data to BμG@Sbase

Corrections to the Newton and Coulomb potentials caused by effects of spacetime foam

We use an extended quantum field theory (EQFT) hep-th/9911168 to explore possible observational effects of the spacetime. It is shown that as it was expected the spacetime foam can provide quantum bose fields with a cutoff at very small scales, if the energy of zero - point fluctuations of fields is taken into account. It is also shown that EQFT changes the behaviour of massless fields at very large scales (in the classical region). We show that as $rgg 1/mu$ the Coulomb and Newton forces acquire the behaviour $sim 1/r$ (instead of $1/r^{2}$)

Interaction of agents and environments

A new abstract model of interaction between agents and environments considered as objects of different types is introduced. Agents are represented by means of labelled transition systems considered up to bisimilarity. The equivalence of agents is characterised in terms of an algebra of behaviours which is a continuous algebra with approximation and two operations: nondeterministic choice and prefixing. Environments are introduced as agents supplied with an insertion function which takes the behaviour of an agent and the behaviour of an environment as arguments and returns the new behaviour of an environment. Arbitrary continuous functions can be used as insertion functions, and we use functions defined by means of rewriting logic as computable ones. The transformation of environment behaviours defined by the insertion function also defines a new type of agent equivalence--- insertion equivalence. Two behaviours are insertion equivalent if they define the same transformation of an environment. The properties of this equivalence are studied. Three main types of insertion functions are used to develop interesting applications: one-step insertion, head insertion, and look-ahead insertion functions

How markets react to earnings announcements in the absence of analysts and institutions evidence from the Saudi market

How stock markets react to news is an established area of research. We examine the behaviour of the Saudi Stock market in response to earnings announcements where there are no analysts’ forecasts, with the aim of examining the efficiency of the market. The SSM seems to underreact to positive news for the first five days and then reactions tend to strengthen in the following weeks, indicating the presence of a post–earnings announcement drift, or PEAD. At the same time, the SSM overreacts to negative news in the first five days and then reverses its direction and reports an upward post-earnings announcement drift. The individually dominated market combined with the absence of analysts’ forecasts is the main explanation for this underreaction to positive news and overreaction to negative news
